Application flied August 18, 1926, Serial No. 188,976, and-.111 Germany August 20, 1925.

This invention relates to an improved device adapted to hold and bring heavy work pieces for instance heavy weldlng-pieces, which must be heated before welding, in any 5 desired position during the welding-process. Hitherto, this was very difficult and only possible by means of devices, which could not be served byfia single person.

According to the present invention said drawbacks are overcome and its novelty consists of a fo dation-plate on which two movable h low shafts are arranged, which cross each other and which are connected together at the crossing-point. Onepf said shafts rests vertically onto a fixed hollow support and is formed in its middle like a cross-piece, the ends of said cross-piece carrying exchangeable handles. Furthermore in said crosspiece a shaft is movably arranged, which shaft carries on one end a counter-weight and on the other end, projecting beyond the vertically arranged shaft,

a flan e with four arms and concentric rings,

on which the welding-piece may be fastened. For hollow pieces, which must be heated before working, the device is furthermore provided with a perforated plate, which can be screwed on the device and which carries supports or the like to hold the cylinder and casing, for which purpose a' mantle of corresponding form is screwed on the perforated plate and adapted to receive the work-piece. After bringing the work-piece into said mantle, it is surrounded with charcoal heating the work-piece when glowing.

A cover serves to close the mantle and 1s held thereon by a chain.

In the accom anying drawing: Fig. 1 is a si e view,

Fig. 2 a top view, and a Fig. 3 a section on the line a;.b of Fig. 1. On a foundation-plate a two hollow supports 6 and c are fastened. In said hollow supports tubes (1 and e are adjustably received, the ends of said tubes being formed as clamping-devices. The tubes d and e are movable in the hollow supports 6 and a, so that they can be brought in. any desired height. In the ends of the tubes at and e,

which are formed as clamping-devices f and g, a hollow shaft it rests and the latter is ,cross-like formed in its middle, to receive the rotatable shaft 5, which latter can be fixed by a handle-screw j. The ends of the hollow u shafts h are provided with four holes, in

ing-piece of the hollow shaft 7t carries on its which right-angled curved armsk and Z are fastened y means of bolts-or the like m and m. The shaft 71 extends through the cross- Said flange is provi' ed with arms 1' and said arms carry concentric rings .9. In the flange screws t of different kind are provided, so. that small work-pieces which do not need to be heated before working, may befastened on the device by any suitable means. In

order to be able to heat the'work-pieces on the device, a plate '12 of sheet iron may be fastened on the flange g by means of the rings 8 and screws 10, M1, on which plate a cylinder or like formed mantle to of sheet iron is provided and which is adapted to receive t e work-piece. Within this mantle a motor may be placed. Within said mantle, the work-piece is surrounded with charcoal and heated through the coals, whereby ten sions in the piece are prevented. A cover serves to close the mantle and is fastened and held thereon by a chain :0.

1 The operation of the new device is as folows:

After the work-piece is brought to a suitable heating-temperature, the mantle is removed from the welding-plate. Then the welding-plate is brought to horizontal po sition, which is done by the flange g, on which the work-piece is fastened. In order to obtain an axial turning of the workpiece, the axle It provided with levers 7c and is turned and held in this position by the clamping-device g. Essentially, the balance is hereby made by the counter-weight n movably and fixabl on the shaft 7;. Said counter-weight n wi 1 hold the work-piece in any osition, in which it is turned, without fixing the latter by the clamping-device g and the handle-screw j.

The new device may be used not only for holding welding-pieces durin the weldingprocess, but it can also be use for any other purpose, for instance as work-plate, mount-- inglate, heavy drawing-board or the-like.

VV hat I claim, is:

1. A device for the purpose described com- 110 prising a foundation plate, spaced apart ollow supports, tubularmembers ad ustable in said vsupports and terminating in tubular portions orming clamping' -devices a hollow shaft" selectively rotatable in sai clamping devices and rlgid with a crossshaped middle"portion,ri ht angled curved arms received 1n the ends of said hollow shaft, a vertically disposed shaft extended through said cross weight carried b sa1d last named shaft; s

2; A device or the vpurpose described comprising a foundation plate, spaced apart hollow supports, tubular members adjustable in said supports and terminating in tubular portions forming clamping devices, a

hollow shaft selectively rotatable in said clamping devices and rigid with across-' 3 shaped middle portion,

ri ht angled curved arms received in the ends of said hollow -shaft, a vertically disposed shaft extended through said cross portion, and a counter weight carried by said last named shaft, and a flange carried by the upper end of said last named shaft.

3. A device for the purpose described comprising a foundation plate, spaced-apart hollow supports, tubular membersv ad ustable in saidv sup orts and terminating in tubular portions ormmg clamping devices,

ortion, and a counter Y a hollow shaft selectively v rotatable in said clamping devices and rigid with a crossshaped middle portion, ri ht angled curved 3 arms received inthe on s of saidhollow shaft, a vertically disposed shaft extended through said crossportion, and a counter weight carried by saidlast named shaft and.

\hollow supports, tubular members ad us t-' able in said sup ortsand terminating in tubular portions orming clamping devlces,

a hollow shaft selectively rotatable in'said clamping devices and rigid with va crossshaped middle portion, ri ht angled curved arms received in the en s of said hollow shaft, a vertically disposed shaft I extendedthrough said cross o'rtion, and a counter weight carried by sald last named shaft, and a flange carried by the upper end of said last named shaft, arms carried by' said and clamping devices co-operating with 'said vertically disposed shaft.v

In testimony whereof I aflix my signature.
